Hi all,
I have just bought a second hand Skymaster F18. My question is this, how much slack can there be in the up/down (vertical) and fore/aft on the elevators. I am not talking of the rotational movement as you get when you apply up or down elevator, more the movement in the bearings, if you know what I mean.
My mate has a couple of hawks that have some slack like mine, but I just want your opinions.

Thanks,
